INTERNAL-COMBUSTION. MOTOR.

Application led June 14, 1917. Serial No. 174,788'.

To all whom it may concernf Be it known that I, WILLIAM J. SNADECKI, a citizen of the United States, residing at Bridgeport, inthe county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Internal- Combustion Motors, of which the following is a specification, reference being had thereinto the accompanying drawing.

- 'My invention relates to improvements in internal combustion engines and more particularly has reference to means in 'combination therewith for cooling the lubricating oil thereof and alsopreferably ,simultanelously heating the air fed to the engine cylinders. Y

vIt is well known that in most types of internal combustion engines that the lubricating oil upon coming in contact with the cylinder walls becomes highly heated there`v by causing various forms of trouble. Well known to those skilledin the art. One of the principal 'objects of this invention .is to provide a suitable and convenient method of reducing the temperature of this lubrieating oil while-at the -same timer utili-zing r 1n a from. l y .Referring tothe accompanying drawings broken away the lower part of an' engine y casin and an' attachment illustrating lan embo iment of my invention, and Fig. 2 is a view looking lfrom right t0 left therea-t.

3 indicates the engine casing beneath the vcylinders and in which it is common practicel to carry. a supply of lubricating oil. 4- indicates a suitable tank or chamber lwhich may be suspended therefrom by brackets 40 vsuc-h as 5 or which may be secured in any Y suitablemanner, and 6v indicates suitable tubes'or passages through which the oil from `the casing 3 may feed into the chamber 4.

practical manner theheat drawn therev I1 have "illustrated in 1- .with parts'y `7 indicates a series 0f tubes engaged in 45 the heads 8--9 forming the ends of the chamber 4, through which air is allowed to pass completely, thus providing a large tubular surface which may be cooled by atmospheric air and which may -be kept in contact with the lubricating oil. From the foregoing it willbe seen that any desired quantity of lubricating oil may be. thus provided for and may be thuskept in con- ,tact With a large surface, thereby insuring a decidedlyv reduced temperature of theoil. 10 indicates a suitable tube provided with a head such as-ll through which the air may be drawn through the tubes 7 for supplying the same' to the carbureter, thus pro- 60 viding a suitable draft and means for canrying o 'lvthe heatedair for advantageous use. Oflcourse it will be understood that any suitable connections maybe made with the chamber `4 for providing any; well G5 known or desirable circulation of the oil therein, and of course it will be understood that various modifications may be made'in `the construction and arrangement of parts without departing fromJ the spirit of the invention as claimed.

ber and said crank case forthe circulation y of air. In testimony whereof I hereunto aix my. signature in the presence of two witnesses.
